This work is devoted to the study of coatings on Incoloy 825 and highentropic alloy FeNiCoCrMo0,5 obtained by powder alitization. The tasks that were solved in the course of the study were: 1. To produce coating on the samples by changing samples and temperature. 2. to determine the influence of various parameters on the structure and properties of the obtained materials. In this work, studies and calculations showing on the microstructure and properties of the coatings were carried out. The analysis was carried out using SEM, X-ray structural analysis. As a result of the work, the dimensions of the obtained coatings at different temperatures and their phase compositions before and after heat treatment were analyzed. When considering Incoloy and high entropy alloy, it was found that the coating on VES at 800°C has the highest microhardness of about 754±20HV, and its thickness reaches 50±5μm, compared to other samples. However, closer to the surface, the hardness of this sample decreases to â“336HV, while Incoloy 825s hardness from the surface changes from 544HV to 706HV. The surface of Incoloy 825 sample at 800°C did not degrade during indentation compared to other samples and its coating reaches 40±5μm. The smallest coating was obtained for Incoloy 825 at 600 ° C and FeNiCoCrMo0.5 at 700°C was less than 5µm.
